3 HVAC Myths You Might Not Realize Are Untrue

Get the facts about your heating and air conditioning system.

HVAC, heating and cooling

With so much information readily available online, it’s easy to fall for fake news. When it comes to HVAC, those misconceptions may just be costing you money. Below are some common ideas about central heating and cooling that we often run across with our customers.

Myth #1: Your air filter only needs to be changed once a year.

This may work if you live in a pristine mountain community where there’s never been a fire, smog is non-existent and all indoor pets wear special suits to prevent shedding and dander (when you find that place, let us know where it is so we can move there!). However, in the real world of Southern California, smoke, pollution, and other environmental irritants run rampant in the air we breathe. Your air filter is designed to prevent many of those contaminants from reaching your indoor living area, but it can only do so much for so long. Worse, when a filter gets clogged, it slows down regular airflow and impedes your system from heating and cooling effectively. Your equipment ends up with more wear and tear, and your indoor air quality suffers. Moral of the story? Change your air filter every 30 days if necessary, and at least every 3 months. Your lungs, and your heating and air conditioning system will thank you.

Myth# 2: Bigger Is Always Better When It Comes to HVAC

It seems reasonable that when you’re adding central air, you should purchase a bigger unit that is designed for heating and cooling even more square footage than you actually have, right? We get it! But the fact is that installing a bigger system than you need results in less efficient HVAC. Your system may not heat and cool your space properly, and it will definitely cost you far more than necessary to do so. The solution? Consult an HVAC professional before purchase. There are simple, industry-standardized calculations they can use to determine the optimally sized unit for your home. In doing so, you’ll enjoy lower energy bills and greater HVAC energy efficiency for years to come.

Myth #3: If It Ain’t Broke, Don’t Fix It

It’s good advice for many things, but just doesn’t apply when it comes to HVAC. Your heating and cooling system needs regular maintenance in order to perform at its best. A twice-yearly inspection can prevent larger, more expensive problems down the road. Your HVAC technician will check for leaks, inspect all equipment, swap out filters, fix dry joints and basically keep your heating and air conditioning running smoothly. You wouldn’t avoid scheduled service for your car; don’t make that mistake with your HVAC system.

Sadly, these myths are far too common, leading to greater energy waste, higher utility bills and HVAC systems breaking down sooner than they should. Get the real story. Your HVAC will not only last longer, but save you real cash, too.
